I have a couple pcs here have a dedicated Esata port on motherboard. I
also have a number of Sata hard disks just sitting unsued on a shelf.

I'm wondering if it's ok to run a standard usb cable from the Esata
connector out the back of a pc and connect it to a regular Sata drive.
I'd of course give it it's own power supply using a "special" cable I
already have.
